Rigid connection joint of steel tube concrete pile and steel beam

Abstract

The invention relates to a rigid connection joint of a steel tube concrete pile and a steel beam in a steel tube concrete structure system. The steel tube concrete pile intersects with the steel beam; the steel beam extends inwards the steel tube concrete pile; end parts of upper and and lower flange plate extension sections of the steel beam inside the steel tube concrete pile are respectively connected with end plates; upper and lower reinforcing rings are coaxially arranged inside the steel tube concrete pile and are respectively connected with an upper flange plate extension section and a lower flange plate extension section at a plane; and peripheries of an upper reinforcing ring and a lower reinforcing ring are connected with an inner wall of the steel tube concrete pile at the plane. With the adoption of the rigid connection joint, the joint is stressed more reasonably, safely and reliably; construction becomes more convenient; quality is ensured more easily; and an economic performance is improved significantly.

Description

technical field [0001] The invention relates to the field of civil structural engineering, in particular to a joint form adopted for rigid connection between a steel pipe concrete column and a steel beam in a steel pipe concrete structure system when the steel pipe concrete column is arranged. Background technique [0002] The steel tube concrete structure has the advantages of high bearing capacity, good seismic performance, and convenient construction. It can adapt to the needs of modern engineering structures to develop into large-span, high-rise, heavy-load and withstand harsh conditions, and meets the industrial requirements of modern construction technology. Therefore, in the past ten years It has been popularized and applied in high-rise buildings and has developed very rapidly. [0003] In the CFST structure, when the diameter of the CFST column is small, the rigid connection between the steel beam and the CFST column can be connected by an external reinforcement rin...

AI Technical Summary

Problems solved by technology

[0004] According to the existing literature, when the internal reinforcement ring connection method is adopted in the larger-diameter CFST column, since the slab width of the reinforcement ring must be greater than or equal to 0.25 times the diameter of the CFST column, the amount of steel used in the joint area is relatively large, and the economic performance Poor; at the same time, when the width of the inner reinforcing ring is large, it will affect the pouring quality of the concrete in the steel pipe column
